FULCRUIVI FOR BRAKE-BEAMS.

SPECIFICATION forming part of Letters Patent No.' 594,384, dated November 30, 1897.

Application led March 15, 1897.

.To all whom, it may concern:

Be it known that I, FRANK W. COOLBAUGH,

a citizen of the United States, and a resident of Easton, in the county of Northampton, in the State of Pennsylvania, have invented certain new and useful Improvements in Fulcrums for Brake-Beams, of which the following is a specification.

This invention relates to improvements in brake-beams, and especially to brake-beams of that kind which are composed of a single section of rolled metal-such as, for example, a T-beam or so'called deck-beams -0n the ends of which beam-section the brake-heads are fastened.

The object of my invention is to provide a new and improved fulcrum for such beams, to which fulcrum the brake-lever isto be pivoted, said fulcrum being simple in construction, strong and durable, can readily be applied, and its parts more readily adjusted in place than the parts of the fulcrums used heretofore.

In the accom an in@ drawings forminfr a part of this specication and in which like letters of reference indicate like parts in all the views, Figurel is a plan view of a brakebeam provided with my improved fulcrum. Fig. 2 is a perspective view of one section of my improved fulcrum on an enlarged scale. Fig. 3 is a vertical transverse sectional view on the line 3 3 of Fig. l, also on an enlarged scale.

The brake-beam A is composed of rolled metal provided along its inner edge with ilanges B,`projecting from the upper and lower surfaces of kthe web A'L The brake-heads C are suitably fastened on the ends of the beam.

The fulcrum D, to which the brake-lever is to be pivoted, is composed of two like sections D, of which one is placed on the upper and the other on the lower surface of the web, and which are then secured on the web. Each section D' has a body portion E, provided v with a recess or pocket F for receiving part of the flange B of the beam, and from said body portion a wing G extends to the rear in such a manner that when the section is placed on the beam and the ange B passes into the said pocket the wing G rests flat on the web.

The two sections D are then held in place on Serial No. 627,562. (No model.)

the beam by means of a rivet H, which is passed through holes G in the wings G and through the beam. The sides of the body portion are strengthened by flanges or ribs I, cast integral therewith. From the front of each body portion a Wing K projects, which is at an inclination to the plane of the wing Gr of about forty-tive degrees, and between which wings K of two body sections the brakelever is pivoted by means of a bolt passed through the holes L in the outer ends of the wings and through the brake-lever placed between said wings. Each wing K is provided at its rear end with an inclined flange M, which flanges abut when the two sections are applied on the beam.

From the inner surface of each wing K a neck N projects, and from each neck an angular rib P extends to the bottom edge of the wing, and when the two sections are applied on the beam the ends of necks N abut and form a tubular guide and receptacle for the rivet R,`by which the two wings are held together. Thereby the two wings are held the proper distance from each other, so as to leave the proper space for t-he play of the brake-lever, and at the same time a guide is formed for holding the rivet R and preventing the same from bending or bulging between the wings while being headed up. Furthermore, the parts are held in proper position, so that the holes L for the brake-beam bolt are directly opposite each other, thus greatly facilitating the inserting and pivoting of the brakelever.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination with a brake-beam of two fulcrum-sections secured on the same, each section having an inclined projecting wing provided on its inner surface with ak neck, the ends of the necks on the two wings abutting when the sections are secured on the beam, substantially as herein shown and described.

2. The combination with a brake-beam, of two fulcruIn-sections secured on the same,

Veach section having an inclined projecting wing provided on its inner surface with a neck and a rib extending from the neck to the edge of the 'wing and the free ends of said IOO through the rear Wings and the web of the beam and a rivet passed through the abutting necks on the front wings, substantially 15 as herein shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of tivo Witnesses, this 11th day of J anuary, 1896.
